Bilateral arthrography of the wrist

In order to determine the true significance of a positive arthrogram in the investigation of wrist pain, a prospective trial was carried out in 60 patients, using the opposite asymptomatic wrist as a control. Of the 46 patients with positive findings in the symptomatic wrist, 34 (74%), had positive arthrograms in the opposite, asymptomatic, wrist. As a result of this, we conclude that a unilateral arthrogram is of little diagnostic value and we recommend the use of the opposite, asymptomatic, wrist as a control.     

Radial shortening for Kienb?ck's disease: factors affecting the operative result

The operative results of radial shortening in 23 patients with Kienb?ck's disease were analysed on the basis of age, stage of disease, ulnar variance and the amount of radial shortening. The patient's age was found to be the factor which affected the operative result most and unsatisfactory results were obtained in patients over 30 years old. However, neither the clinical stage nor ulnar variance affected the results significantly and the results in patients with ulnar zero or plus were no worse than in patients with ulnar minus. The risk of ulnar wrist pain was increased when the radius was shortened more than 4 mm in patients with positive or zero ulnar variance. This was an important cause of unsatisfactory operative results.     

The relationship between neuropsychological function and brain damage detected by neuroimaging after closed head injury

Studies relating neuropsychology and structural neuroimaging after closed head injury are reviewed. Particular attention is given to the question of the relative contribution of focal and diffuse damage to neuropsychological impairment. The evidence currently available emphasizes the importance of diffuse damage in closed head injury. Diffuse damage is not equally distributed in the brain, and the review suggests three axes that are relevant for neuropsychological function: (1) damage may be unilateral or bilateral, (2) damage is characteristically greater in anterior regions than posterior regions, and (3) damage shows a centripetal gradient. A large gap remains between the emergent generalizations concerning head injury and reliable neuropsychological interpretation of scans from individual patients.     

Hand infections in the diabetic and the diabetic renal transplant recipient

We present a series of 41 diabetic patients with severe tissue destruction and deformity secondary to hand infections. Thirty (73%) of the patients showed propagation of the infection to bone, tendons, or deep palmar spaces, and 26 of 41 (63%) required amputations. Sixty-three percent of the cultures were mixed; pure Staphylococcus aureus accounted for only 12%. Diabetics who were renal transplant recipients were at increased risk, with a 100% amputation rate and an average hospitalization of 41 days. Recommendations for management of diabetic hand infections are given to reduce the mortality and morbidity in these patients.     

Techniques of splenic preservation using fibrin glue

Fibrin glue (FG) was used to achieve hemostasis of 16 splenic injuries in 14 patients. The etiologies of injury included five gunshot wounds, two stab wounds, four iatrogenic injuries, and five patients with blunt splenic trauma. The intraoperative blood loss averaged 1.8 +/- 2.4 (SD) liters and patients were transfused 3 +/- 2 units of blood perioperatively. The amount of FG required to achieve splenic hemostasis averaged 11 +/- 8 ml and varied directly with the grade of injury. One patient with a splenic hilar vascular injury (Grade V) underwent splenectomy following failure to achieve complete hemostasis despite the use of 25 ml of FG. All other splenic injuries were successfully managed using less than 25 ml of FG. Postoperative computerized tomographic (CT) scanning, performed in ten patients, was negative for rebleeding or abscess formation. The overall splenic salvage rate was 86%. FG was effective in achieving hemostasis of both superficial and deep splenic injuries. Its use as an adjunct in trauma surgery should result in increased splenic salvage rates compared with that obtained using conventional surgical techniques.     

Perforation of hepatic hydatid cysts into the abdominal cavity in children

Perforation of echinococcal cysts of the liver into the free abdominal cavity was observed in 10 patients. The operative intervention was performed after overcoming the shock in patients, correction of homeostasis. The performance of wide laparotomy, through revision of the abdominal cavity and its sanitation by means of the abundant washing by the furacin solution are important. No lethal outcomes, disease recurrences were noted.
